To all whom *z'zfmayconcern: I

Be it known that I, ALBERT H, MORTON, a citizen of the United States,residingvat' Lowell, in the county of Middlesex and State ofMassachusetts,Lhave invented certam new and useful Improvements inGarding-Engines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such aswill enable othersskilled in the art to which appertains to, make and use the same.

The present invention relates to an improvement in carding engines.

The improvement in carding engines,

illustrated and described in my co-pending application, Serial No.7,923, contemplated specifically the application of the driving power tothe top flats within theiperiphery of the top fiat disks and at the toponly of, the disks so as to cause the top flats to be adapted for newwork.

It is the object ofthepresentinventionto" provide a construction andarrangement of parts which is especially adapted'for incorporation inexisting machines, and which will enable the vabove improvement to bereadily and conveniently applied to such machines at a minimum expense,and without change in the top flat chains or in the positions of thesprocket shaft and stripping comb or in the driving connections for theshaft and comb.

To these ends the invention consists in the features of construction andcombinations and arrangements of parts hereinafter described andparticularly defined in the claims.

In the accompanying drawing illustrating the preferred form of theinvention Figure 1 shows a portion of the main cylinder, the top flats,the top flat chain sprocket and associated parts, and Fig. 2 is avertical section of a part of the bracket, the eccentric, the disk, andthe sprocket.

The illustrated embodiment of the inven- The construc-' tion thereinlllllStlZLtGCl, however; was only,

manner with the top flat chain 10, which flats are driven by thesprocket wheel 11 mounted upon the sprocket wheel shaft" 12 and heldagainst relative movement thereto by the key 13. The top fiat disk 1% isrotatably mounted between the bracket 15 and the sprocket 11 upon aneccentric 16 supported upon the sprocket wheel shaft,

and held from rotation by the pin 17 by which the eccentric is securedto the bracket 15. The eccentric 16 is provided with a shoulder orflange 18 which engages one side of the hub of the top fiat disk. Theother side of the hub of the top flat disk engages the hub of (thesprocket .wheelll. These two parts, therefore, maintain the top flatdisk The traveling flats 8 are articulated in the usual,

from the endwisemovement on the sprocket wheel shaft. It will beobserved that the top ii at disk let supports and moves with the topflats, and at a difierent rate of surface speed from that of the pitchline of the top fiat sprocket 11. The only changes necessary to be madein the carding engine for the pur= pose of adapting the use of thisinvention" thereto is to drill a hole in the bracket 15 to receive thepin 17 to apply the new partsthe sprockets, eccentrics and the disks.This makes, therefore, a very inexpensive construction for changing overexisting Ina-'- chinesto embody the invention of the said applicationSince in changing over existing machines the old top fiat chains areretained, the pitch of the new sprocket 11 will be determined by thepitch of these chains, while its diameter must be such that its lowerportion will clear the lugs on the flats. The eccentric 16 is soconstructed and arranged that its center is in, or substantially in, aline bisecting the angle between a line passing through the centers ofthe sprocket shaft and main cylinder and a line passing through thecenter of the sprocket shaft and the point of operation of the strippingcomb. This construction. and arrangement of the eccentric enables thedisk to be so proportioned thatthe position of its surface at the linepassing through the centers of the cylinder and sprocket, and at thepoint of operation of the stripping comb, will prac- 1 tically coincidewith the position of the surface of the old disk at these points, sothat the top flats will be accurately positioned to cooperate with themain, cylinder at the point where the flats leave the cylinder, and

to cooperate. with the old stripping comb.

The disk is made of such a size that its surface will coincide with thesurface of the old disk at the points above referred to, and will alsoso support the top flats'that the pitch line of the lugs on the flatswill properly coincide with the pitch line of the sprocket at thatportion of the disk surface which coincides with the driving. portion ofthe sprocket. With the disk thus proportioned and mounted upon aneccentric constructed and arranged as described, the surface of the topflats will not only be in practically the same position at the pointsreferred to as when supported upon the old disk, but

will. also betraveling in practically the same directions at thesepoints, and thus the proper cooperation of the old top flats with theold main cylinder and stripping comb is claimed is:

1. A carding engine, having, in combination, a main cylinder, revolvingtop flats, a top fiat sprocket and shaft, a disk for supporting the topflats, a bracket, an eccentrio pinned to the bracket and affording asupport for the top flat disk eccentric to the top flat sprocket shaft.

2. An eccentric for use in reconstructing carding engines provided witha hole to re ceive the pin by which the eccentric is pinned fast tothebracket, and an eccentric surface to receive the top flat disk.

3. An eccentric for use in reconstructing carding engines provided witha hole to re-.

hole to receive the sprocket wheel shaft of thecarding engine, and asurface to receive the -top flat disk, combined with a device forsecuring the eccentric to the bracket of a carding engine. 7

5. Mechanism for reconstructing top flat drives of carding engineshaving top flat supporting disks and top flat sprockets, comprisingtopflat driving sprockets adapted to be secured to the sprocket shaft ofthe machine, and of a size to engage the top flats near the top only ofthe top flat disks, top flat disks and eccentric bearings for the topflat disks constructed to support the disks with their surfaces at thepoint where the top flatsleave the main cylinder and at the point ofoperation of the stripping comb substantially coincident with thepositions of the surfaces of the old disks at these points.

6. A carding engine, having, in combination, a main cylinder, astripping comb, revolving top flats, a disk for supporting the topflats, a sprocket for driving the top flats,.and an eccentric bearingfor the disk having its center substantially midway between a linepassing through the centers of the sprocket and main cylinder and a linepassing through .the center of the sprocket and the point of operationof thestripping comb.
